Biological floating island with automatic sunshade function

Abstract

The invention discloses a biological floating island with an automatic sunshade function. The biological floating island comprises a biological floating island, wherein a hollow tube is fixedly connected with the center of the upper end of the biological floating island; a glass cover is mounted at the upper end of the hollow tube; a shape memory alloy is fixedly connected with the top inside theglass cover; a rotating rod is fixedly connected with the lower end of the shape memory alloy; the lower end of the rotating rod extends into the hollow tube; a plurality of arc-shaped holes are formed in the side wall of the hollow tube at equal intervals in a circumferential direction; fixing rods are fixedly connected with side walls of the hollow tube between two adjacent arc-shaped holes; a plurality of pull rods are fixedly connected with the side wall of the rotating rod in the circumferential direction; tail ends of the plurality of the pull rods respectively penetrate through multiplecorresponding arc-shaped holes; and opposite side walls of the pull rods and the fixing rods are both connected with folding sunshade cloth. The biological floating island is reasonable in structure,and the folding sunshade cloth can be automatically opened to shade sunshine in case of intensive sunshine and high temperatures.

Description

technical field [0001] The invention relates to the technical field of ecological floating islands, in particular to an ecological floating island with an automatic sunshade function. Background technique [0002] The ecological floating island is an artificial floating island that aims at eutrophic water quality and uses the principle of ecological engineering to degrade the content of COD, nitrogen and phosphorus in the water. It can greatly improve the transparency of the water body, and at the same time, the water quality index has also been effectively improved, especially for the inhibition of algae. The main effect of ecological floating islands on water purification is to use the roots of plants to absorb eutrophication substances in the water, such as total phosphorus, ammonia nitrogen, organic matter, etc., so that the nutrients in the water body can be transferred, and the water body can be reduced due to closed or insufficient self-circulation. Odor and eutrophi...

Problems solved by technology

[0003] At present, most of the plants planted on the ecological floating island are aquatic plants. In summer when the sun is strong, the temperature is very high, especially at noon, when the sun is the strongest. Plants exposed to the sun for a long time are prone to sunburn, and even It will lead to the death of plants, and because the floating island is floating on the water, it is not easy to build a sunshade.
